Acenes have received a lot of attention because of their inherent and tunable absorbing, emissive, and charge transport properties for electronic, photovoltaic, and singlet fission applications, among others. Such properties are directly governed by molecular packing, and therefore, controlling their arrangement in the solid state is of utmost importance in order to increase their performance. Herein, we describe a new solid-state ordering strategy that allows obtaining 1D mixed π-stacks of acene and azaacene derivatives. In addition, we illustrate that charge transport can be modulated by the electronic nature of the encapsulated phenazine, opening new perspectives in the design, preparation and development of supramolecular organic semiconductors.
由于并苯具有固有的、可调节的吸收、发射和电荷传输特性，可用于电子、光伏和单线态裂变等应用，因此受到了广泛关注。这些特性直接受分子堆积的影响，因此，控制它们在固态中的排列对于提高其性能至关重要。在此，我们描述了一种新的固态有序策略，该策略允许获得并苯和氮杂并苯衍生物的一维混合π堆积。此外，我们还表明，电荷传输可以通过封装的吩嗪的电子性质进行调节，这为超分子有机半导体的设计、制备和开发开辟了新的前景。
